The striker was substituted during Liverpool's 2-1 win against Chelsea at Stamford Bridge.

Liverpool have injury doubts hanging over Daniel Sturridge and Adam Lallana heading into their Premier League fixture against Hull City on Saturday (24 September). The duo both missed the Reds' 3-0 win against Derby County in the EFL Cup on Tuesday (20 September) and manager Jurgen Klopp has admitted he remains unsure if they will be fit for the weekend.

Klopp revealed he will wait to see how the England pair – who are currently carrying minor knocks – perform in training over the next couple of days before he decides if they are available for selection. Sturridge has not trained for the last week after experiencing some "issues" in Liverpool's impressive victory against Chelsea at Stamford Bridge, when he was substituted in the 57th minute.

Asked whether he expects Sturridge to be fit this weekend, Klopp said, according to The Mirror: "I think so. But it depends on the training. Same with Adam, he felt the intensity of the last few games. No need to try anything with him [vs Derby]. But it's different. We have another two days and we will see."

Klopp also insisted he has no problem keeping his attacking players happy, despite the intense competition for places at Anfield. Liverpool supplemented their attacking options over the summer with the signing of Sadio Mane from Southampton, but Klopp sees the increased competition as a "luxury".

"It's not a problem. If the expectation is that every player has to be happy every day, then I know I can't do it," the Liverpool manager shared. "It's the players' problem, not mind. You have different jobs to do, you have to perform when on the pitch. When in training. That's how football is. I don't think it's a problem for us. It's a luxury. All good."
